Inductors

Inductor

Instantly store and releases energy

 

Water pipe

Reducer: Resistance

Water wheel: can rotate when water go through it

First it has resistance so energy keeps inside, but once the water pressure goes over the water wheel can stand, then water wheel start to run with less resistance.

Although pump stops pumping the water from the start, the water wheel plays a role as a pump and pumps the water to other branches until the reducer dissipates the energy.

 

1) Inductors don't like change, they want to remail the same.

2) When current increases they try to stop it with an opposing force.

3) When current decreases they try to stop it by pushing electrons out, to try and keep it the same as it was.

 

Where do we use the inductors?

1) We use them in boost converters to increase the DC output voltage.

2) We can use them to choke an AC supply and allow only DC to pass.

3) We use them to filter and separate different frequencies.

4) We also use them for transformers, motor and relays.

 

The higher the inductance, the higher energy it stores.

 

RLC meter can handle the measure of the inductance.
